Ilya Kovalchuk scored for the Kings, who have lost four of six (2-3-1). Jack Campbell stopped 21 shots for Los Angeles.

Maple Leafs coach Mike Babcock announced Sparks as the game’s starter ahead of No. 1 goalie Frederik Andersen after the morning skate. Toronto then announced about 2 1/2 hours before puck drop that Andersen has a lower-body injury and is listed as day-to-day.

Maxime Lajoie scored in the second period, and Brady Tkachuk, Mikkel Boedker and Zack Smith all tallied in the third for the Senators.

John Klingberg had the lone goal for Dallas, which was playing its first road game after opening the season with four at home. Ben Bishop made 21 saves while losing in regulation against Ottawa for the first time (9-1-4) in his career.

With the score tied 1-1, the Senators went ahead for good early in the third as Dylan DeMelo put a shot on goal and Tkachuk, right in front, redirected it past Bishop at 1:27.
